I suggest you don't use the instant exchange service if you're fine with KYC. In addition to being more expensive, I can't trust them with my card/KYC data. I'd rather use a CEX or other centralized services if KYC is not a problem.
I can neither trust instant swap services nor centralized exchanges with my credit card details after some centralized exchanges will still demand for ID document verification before someone can be able to make a purchase. Truly centralized exchanges are cheaper while buying cryptocurrencies, in this case if WAXP and many other altcoins, you can easily send the WAPX or many other altcoin to noncustodial wallet with just low fee, but it will require high fee for bitcoin.Just make sure whenever you are forced to use these services, like I do, that you also request for their privacy policy. Then, after you've finished using the service and you don't want them to keep your data, request they remove it and delete it permanently with proof. Otherwise, you threaten them (and this is real) with reporting to EU (even if you're not EU but the service serves EU people then it has to comply). This is privacy legislation that works these days.
It works for me at one exchange I didn't use anymore. They deleted and showed proof. Doesn't mean it's really gone but I feel better about it.
